           Summary: [4.9 Regression] ICE: in fill_vec_av_set, at
                    sel-sched.c:3863 with -m64 after r206174 on
                    powerpc-apple-darwin9.8.0
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

Compiling the test gfortran.dg/pr44691.f with -m64 -O2 -fselective-scheduling2
gives the following ICE

/opt/gcc/work/gcc/testsuite/gfortran.dg/pr44691.f:39:0: internal compiler
error: in fill_vec_av_set, at sel-sched.c:3863
       END

Line 3863 of sel-sched.c is the gcc_assert

          /* A fence insn should not get here.  */
          gcc_assert (!fence_insn_p);
